Comb type cage and double row roller bearing for double row roller bearing

摘要

PROBLEM TO BE SOLVED: To provide a comb-shaped cage for a double row roller bearing capable of preventing difficulty in independent rotation caused by contact of back faces, even when deformation by centrifugal force in accompany with rotation, due to different rotating speed in each row, is found.SOLUTION: Two comb-shaped cages 5 and 5 retain a plurality of rollers 4 in each row, and are disposed in a state that back faces 14 and 14 can be kept into contact with each other. A longitudinal cross-section of an annular portion 10 has the circular arc-shape at a radial outer side at a back face 14 side, and a radial inner side of one side face 11 side has the circular arc shape.
